CONDENSER.

SPECIFICATION forming part of Letters Patent No. 550,143, dated November 19, 1895.

Application filed June 19, 1895. Serial No. 553,35 3. (N0 model.)

To aZZ whom it may-concern:

Be it known that we, MICHAEL SPELMAN,

WILLIAM H. GRAVES, and JAMES V. SPEL MAN, of Shreveport, in the parish of Caddo and State of Louisiana, have invented anew and Improved Condenser, of which the following is a full, clear, and exact description.

Our invention relates to improvements in steam-condensers; and the object of our invention. is to produce a very simple and inexpensive condenser, which is adapted to 0011- dense exhaust-steam at a relatively high temperature, and which therefore is adapted to condense the steam without exerting any excessive back-pressure on the piston of the engine.

A further object of our invention is to pro.- duce a condenser which can be readily taken apart and cleaned, and which has a convenient means of carrying away the water of condensation.

To these ends our invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a central vertical section on the line 1 1 of Fig. 2 of our improved condenser, and Fig. 2 is aplan view of the same. Fig. 3 is a view showing a modified form of the device.

The condenser has a shell formed of two parts 10 and 11, which are united by means of flanges 12 and bolts 13, although the parts may be united in any convenient manner,

and these parts are oppositely tapered, the

receiver 14 is supported by means of arms 16,

Above the receiver is a perforated distributer 17, which is in the form of an inverted cone and extends across the top of the shell, this distributer having a central opening 18 at the bottom and being supported by arms 19, which are secured to the distributer and to the top 11 of the shell. The distributer 17 is arranged immediately below a deflecting cone 20, which is preferably at right angles to the top portion 11 of the shell, and this deflecting cone is open in the center.

The exhaust-pipe 21 delivers into the condenser immediately below the receiver 14 and the drain-pipe 22 opens from the bottom of the shell and is adapted to convey the water of condensation to any desired point. WVhen the steam enters the shell, it is delivered against the point of the receiver 14, and is so divided and sent in a thin stratum up the wall of the shell, and when it strikes the deflecting cone 20 it is forced downward through the distributor 17, thus subdividing the steam to a great extent and throwing it evenly throughout the whole upper part of the shell, which action causes it to condense rapidly, and the greater part of the water is caught in the receiver 14: and flows out through the pipe 15 and the drip-pipe 22.

It will be seen that the arrangement is such that the steam is greatly subdivided, and so is condensed at a comparatively high temperature, and therefore there is no great amount of back-pressure on the engine-piston.

In Fig. 3 we have shown a somewhat modified construction of the condenser, wherein the top of the device is provided with aconical cover 23, having a central perforation, wherein slides a vertical perforated tube 24, arranged in the axis of the condenser and adapted to be raised or lowered, so as to more or less fully close the outlet from the condenser. By this arrangement it is evident the degree of condensation may be varied at will to secure the. best results.

It will be understood that the receiver 14, in addition to forming a deflector or divider for the steam discharged from the pipe 21, serves, owing to its inverted conical disposition, to receive and contain. some of the water of condensation, and this becomes cool, so as to keep the surface of the receiver cool and more effectively condense the steam which engages it.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- ,r

A condenser, comprising a two part shell tapering toward its ends andhavin g a steam supply opening at one end, a receiver within the part adjacent to the steam supply opening and tapering toward the same, an over- ;liow pipe for the receiver, a discharge pipe for the shell and adjacent to the steam sup- 15 ply opening, a distributor above the receiver and shaped as a cone and perforated, and a cone above the (listributer, the same being open at each end and communieatin g with the outer side of the shell, substantially as de- 20 W.
